A wrap up of my thoughts around the concept of virtual conferences including first conclusions from comparing to on-site conferences.

Building PDF documents via Sphinx depends of LaTeX being available, this resulted in quite heavy container images which took also very long to build. Out of curiosity I tested to build a minimal Texlive environment based on Nix and got surprisingly nice results, both the image size and the build time dropped significantly.

Small snippet how to run a command with a few extra dependencies inside of the environment in an ad-hoc fashion.

NixOS allows to easily build images of a machine configuration. This post shows in an example how to build a more recent version of the base image which NixOPS uses to spin off Virtualbox based machines. The idea should be applicable to all kinds of machine configurations.

Installation of minikube on OSX via Nix.

Quick note about the attribute "defaults" in a NixOPS network description.

My personal review of NixCon 2017 in Munich. It's about topics I discussed, people I did meet, experiences I made and a few thoughts which I took with me.

When experimenting with NixOS containers, it is sometimes quite nice to just build the container derivation and inspect the result. Being able to use the remote building features makes this even more convenient.

Wrap up of the second hackathon day after NixCon 2017.

A quick example about how to use the library function remove to adjust a package's dependencies based on a given condition.
